Crab allergy is a kind of shellfish allergy, which can range from mild to serious reaction. While some people suffer from rashes, others may suffer from severe symptoms such as gastrointestinal problems and dizziness. People with crab allergy might be allergic to other shellfish and should be careful while eating out. They should also carry an epinephrine along with them to prevent a possible severe allergic reaction.
Crab allergy is caused due to the compound tropomyosin present in the crab. As this compound is also present in other shellfish, people with crab allergy might also be allergic to other shellfish.
Symptoms of Crab Allergy:
People can develop crab allergy by eating or touching the crab. Inhaling the vapors of the crab cooked dish can also trigger an allergy. Here are a few symptoms of crab allergy:
- Rashes
- Hives
- Watery eyes
- Runny nose
- Abdominal pain
- Diarrhea
- Dizziness
In rare cases, eating crab can cause anaphylaxis – a severe allergic reaction. Anaphylaxis can cause dizziness, low blood pressure, breathlessness and it can also be fatal. Injecting epinephrine immediately can prevent the anaphylaxis.
Crab Allergy Treatment:
For allergy treatment, taking anti-histamines can be helpful in relieving the reaction. Epinephrine should be injected immediately if the allergic reaction progresses to dizziness and breathlessness. The injection can prevent anaphylaxis.
Tips to Prevent Crab Allergy:
- Be careful while eating out – inquire about the ingredients and beware of cross-reaction (cooking different foods in the same dish)
- Read the food labels while shopping for food products
- Avoid cross-reaction while cooking at home
Do you have crab allergy? If you are confused, you can consult a allergist, who would then conduct a skin prick test or blood test (RAST) to see if you have crab allergy. So, get diagnosed and take the proper treatment and precautions to overcome crab allergy.
